The length of a rectangle is 4x meters and its width is 5x meters determine the value of x and the width if the perimeter of the
rectangle is 54 meters.
x=
width=
1 answer:
Answer:
x = 3
width = 15
Step-by-step explanation:
perimeter of a rectangle = 2 * width + 2 * length
54 = 2 * width + 2 * length = 2 * (4x) + 2*(5x) = 8x + 10x + 18x
54 = 18x
divide both sides by 18 to isolate x
x = 3
width = 5x = 5 * 3 = 15
